摘要
介绍了萃取精馏法、吸附蒸馏法和膜分离法等用于异丙醇-水分离的新进展,并对这几种方法进行了简单评述,具体分析了各种方法的优缺点,展望了异丙醇-水分离新工艺的前景,认为以乙二醇为萃取剂的萃取精馏技术具有推广价值.
New research advances in separation isopropanol from aqueous solution using extraction distillation, adsorptive distillation and membrane separation are introduced. These measures are briefly commented as well. Their advantages and disadvantages are discussed specifically, the future of isopropanol dehydration technology is prospected, extraction distillation adopting ethylene alcohol as extracting agent is recommended.
